IMPROVEMENT IN PLOWS. Y

Specification forming part of Letters Patent No. l9,750, dated January99 1878 application filed 1 I October 26, 1877. p

. To all who m it may concern Be it known that I, .ARGHI ALD Sum, of

1 River Bank, in the county of Rockingham and .State of Virginia, haveinvented certain .new

it pertains to make and use it, reference being had to the accompanyingdrawings, which form part of this specification.

My invention relates to improvements in plows, and more especially tothat class of the same which admit of certain of the working parts beingremoved and substituted byother parts and it consists in theconstruction hereinafter described and claimed.

In the drawings, Figure 1 represents a plow made according to myinvention, with certain of the detachable parts secured thereto inplace. Fig. 2 shows the plow when adapted to act as a single instead ofa double plow, as shown in the former instance. Fig. 3 is a view showingthe stock parts of the plow free from the working parts, while Fig. 4represents the 7 several different detachable working parts which may beused in plowing, as desired.

The standards A are pivoted to the single beam B at suitable pointsthereon, and are made with the right-angular shoulders a in the upperportions of their respective bodies, while below the said shoulders acurve is made in the line of direction of their length, which causes thestandards to have an inclined seat, I), as the bearing for the upperworking parts of the plow. The lower extremity of each standard isprovided with the forward projecting catch 0 and the rear lug c, theformer being adapted to engage with a suitable slot in the share C,while the lug 0 is tapped and adapted to receive a nut after beingpassed through the second slot in the said share.

This share is adapted to engage with the shovel D by the lug cl fittinginto the upper central hole or opening 01' in the share, while itsopposite body portion is made with the shank d which is clamped by thelink E to the front side or seat b of the standard. The links E areloosely engaged with their respective swinging braces F, which latterare pivoted by suitable means to the beam at proper distances in frontof the attachmentsof the standards thereto. vWedges G, provided withupper body slots, permit the set-screws H to pass. through the same, andhave end bearings against the rear sides of the standards, while theirlower end bodies are formed with the detent catches. h, which engagewith the gradedseries of grooves h on the standards.

As boththe standards and their connecting-braces are all. respectivelypivoted to the beam, any adjustment in the angularv inclina- ..ti0n,ofthe standards to the beam can readily be made, and the parts be swung ormoved upon their pivotal connections, as desired. The link E retains theshovel by means of the wedge engaging on the rear side of the standard,together with its detent-catch and connecting set-screw. The link andbrace accomplish a threefold result, in that they brace the standard,secure the shovel thereto, and regulate the vertical adjustment of theplow, so that the latter may cut a deep or shallow furrow-slice.

The share and shovel shown in Fig. 1 of the drawings only represent oneuse of my plow, while the latter may be used with the other anddifferent working parts shown in the remaining figures. By removing thesaid share and shovel, which are readily detachable, as set forth, anyof the other parts may be substituted therefor. Thus the mold-board L,with its point I made in single piece, may be attached alone to one ofthe standards, as shown in Fig. 2, which might be desirable in heavyplowing and when subsoiling. But if it is not wished to subsoil, thenthe mold-board M, made without a point or land-side, could be substi.tuted in place of the shovel shown in Fig. 1, which would cut and turnthe furrow-slice without causing the lower soil to be thrown up onto thesurface; while, if very light work is to be done, the steel bar N can besecured to the standard, being clamped by the link E at its upperextremity, and engaging with the share at its lower extremity, the sameas in the case of the shovel and other substituted parts abovedescribed. This steel bar simply acts as a detachable wearing-surface,to prevent the standard from becoming worn or affected by use when noneof the working parts are secured thereto, as indicated.

The smaller share or point P is to be substituted for theshare 0 when itis wished to work gravelly soil; and it is evident that the same may beused in connection with any of the working parts which are used with theshare 0, as it is adapted for engagement thereto, and also to thestandard in the same manner. So too, it is apparent that any of thesechanges or substitutions may be made with the plow, either as a singleor double plow,

and also that, instead of using but one .or two of these plows, anydesired number of them may be stocked to a suitable frame; In instanceof using but one plow, only one stand- I ard is necessary, and this issecured to the ing no furrow, as the dirt is not thrown up against thecorn or turned over in a furrowslice; while in heavy plowing,subsoiling, or turning ground, the other suitable parts may be used, asbefore described;

Having fully described my invention, what I claim as new, and desire tosecure byLetters Patent, is- I I 1; The combination, with pivotedstandard A, swinging brace F and shovel D, or other substituted plowworking part, as described, of link E and wedgeG, the latter being heldin place by detent h, formed in same piece therewith, and engaging withnotches on the rear side of the standard, together with setscrew H,having end bearing against the latter, substantially as set forth. I

2. The combination, with share 0 or other substituted plow working part,as, described, which engages with catch 0 and lug a, formed on the lowerend of standard A, of shovel D, or similar plow working part, made withlug d, which seats in slot d of said share, the upper shank of theshovel being secured to the standard by the describedvertically-adjustable clamping mechanism, substantially as set forth.

In testimony'that I claim the foregoing I have hereunto set my hand this24th day of October, 1877. i
